The W3C is looking for comments on this Last Call Working Draft of WCAG 2.0. If you find any problematic areas in this document, submit your comments to make the working group aware of them. Don’t wait too long, since the deadline for submitting comments is 31 May 2006. After that date, WCAG 2.0 will move on to eventually become a referenceable recommendation. That will take some time though - at least six months according to the W3C.

After that date, WCAG 2.0 will move on to become the recommendation that will replace WCAG 1.0

Not really. Last Call is only the second step in a 5-step process from Working Draft to Recommendation, so »Last Call« doesn’t mean »Last Chance before it’s done«. It’s only that the Working Group assumes the document to be complete and stable. Note that the document may be sent back to Working Draft status at any point in the process if W3C’s Director thinks that issues haven’t been properly addressed.

Also, WCAG 2 will not really replace WCAG 1 (as in HTML 3.2 vs. 4). If I understand this correctly, version 1.0 will still be a referenceable document once 2.0 is out, in order to be able to make conformance claims for older content.
